Hi Darko
I have this same issue right now and many other people online have been having it too over the past few years. Them not posting on the EA forum doesn't mean it's a hardware issue and not a game issue.
I can run over 20 games at max graphics, 3 games at the same time and yet only Apex is causing this issue. Other than the crashing, it then forces my PC to force restart.
Respawn or EA team needs to investigate this and not suggest ignorant solutions such as "just buy a new GPU" as you are so clearly suggesting here.
A simple google search or twitter search for the error shows that this issue was a larger one a year into the games launch and an actual statement from RESPAWN was made on twitter regarding this.
